Sailing is intrinsically boring. And all those negative ions washing over you tend to make you sleepy. So it is obvious that designers purposely make the seating uncomfortable for crew members. A couch would be a disaster. I would be asleep on it in an instant and would not wake up until I hit some land mass or other immovable object. <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
